Mingora (Pakistan): A man detonated explosives as army troops prepared to storm his hideout in northwest Pakistan on Saturday, killing himself and wounding at least three soldiers, a senior army official said.

The blast occurred outside the town of Bhat Khela in Khyber Pakhtunkwa province after troops acting on a tip from residents surrounded a militant hideout and told those inside to surrender, Brig. Saeed Ullah said. Soldiers killed a second militant in the shootout that followed the explosion.
Ullah said security forces detained five men from the area on suspicion of sheltering the militants, who he said were planning a suicide attack in the Swat Valley. Bhat Khela is located about 30 miles (50 kilometers) west of Mingora, the main town in Swat.

The Pakistani army launched a major anti-Taliban offensive in 2009 in Swat, a one-time tourist haven largely overrun by militants beginning in 2007.
Though the monthslong offensive was hailed a success, militant activity is still reported in the picturesque region and concerns are growing that the insurgents could rise again.
